A kudurru was a type of stone document used as a boundary stone and as a record of land grants to vassals by the Kassites and later dynasties in ancient Babylonia between the 16th and 7th centuries BC. The original kudurru would typically be stored in a temple while the person granted the land would be given a clay copy to use to confirm legal ownership. Kudurrus are often linked to what are usually called "ancient kudurrus", land grant stones from the third millennium (typically Sargonic and Ur III) which serve a similar purpose though the word kudurru did not emerge until the 2nd millennium (Middle Babylonian in fact).

Eriogonum is a genus of flowering plants in the family Polygonaceae. The genus is found in North America and is known as wild buckwheat. This is a highly species-rich genus, and indications are that active speciation is continuing. It includes some common wildflowers, such as the California buckwheat (Eriogonum fasciculatum).

The genus derived its name from the Greek word erion meaning 'wool' and gonu meaning 'knee or joint'. The author of the genus, Michaux, explained the name as describing the first named species of the genus (E. tomentosum) as a wooly plant with sharply bent stems ("planta lanata, geniculata"). Despite sharing the common name "buckwheat", Eriogonum is part of a different genus from the cultivated European buckwheat and than other plant species also called wild buckwheat.
